摘要：
The fault current of DC distribution system rises rapidly after fault occurs, which brings impacts to the power electronic devices. By equipping with CLRs(Current-Limiting Reactors), the rising rate of fault current can be effectively suppressed, the peak value of the fault current can be reduced, and the power electronic devices of the system can be protected. An electrical-magnetic simulation model based on three-phase two-level VSC(Voltage Source Converter) is built. The fault principle and characteristics of pole-to-pole short circuit fault are explored, and the current limiting principle and effect of CLRs at different locations are studied. Considering the flow resistance characteristics of VSC and the action characteristics of protection devices, the method of optimizing the location and parameters for CLRs is proposed. The optimum configuration scheme of CLRs is determined by simulation optimization on PSCAD/EMTDC platform. © 2019, Electric Power Automation Equipment Press. All right reserved.
